After the 46.0.1 update Firefox keeps disabling the Flash plugin every time I start it. I always had it set to "ask to activate," but after the updated I no longer got asked to activate flash on sites with flash or sites where I previously allowed it and set it to remember didn't work properly. I checked the plugins and saw it was disabled, so I set it back to ask to activate. After restarting Firefox it goes back to being disabled and I have to change it every time.
